SYSTEM AND METHOD OF RECYCLING ASSOCIATED WATER FROM WELLS OF CLUSTER PAD Russian patent published in 2020 - IPC E21B43/38 E21B43/40 

FIELD: soil or rock drilling; mining.

SUBSTANCE: group of inventions relates to a system and method for recycling associated water from wells in a cluster site. System for utilization of associated water from wells of cluster platform includes: well separator located in the first well bore of the cluster platform and configured to receive the first produced fluid from the first production zone and formation of the flow with high content of hydrocarbons and water flow from the above fluid, pumps containing the first pump and the second pump. First pump is located in the first borehole of the well and is connected to the well separator, and the second pump is located in the second borehole of the cluster site. System also comprises: first ground separator connected to first pump by first channel and second pump by second channel and configured to receive stream with high content of hydrocarbons from well separator by first pump and receiving the second produced fluid from the second production zone using the second pump and with the possibility of formation of oil and a stream with high water content from the stream with high content of hydrocarbons and the second produced fluid; a first pipe connected to the well separator and configured to remove water flow from the well separator into the first utilization zone, and a second pipe connected to the first ground separator and configured to remove the high water content stream from the first land separator to the second disposal zone.

EFFECT: technical result consists in improvement of separation efficiency.
